Description
Technical field
The present invention relates to a kind of garbage incinerating power plant burner hearth flue temperature detector, more particularly to a kind of waste incineration to send out
Power plant's burner hearth flue thermocouple.
Background technology
Thermocouple is a kind of conventional temperature sensing device, mainly including thermode, insulation tube, metal protective sleeve pipe and wiring
Box, thermode and insulation tube are placed in metal protective sleeve pipe.Refuse-burning plant is needed largely using thermocouple to burner hearth, cigarette at present
The temperature in road measures, it is generally the case that the vertical flue of every refuse-burning plant incinerator needs installation ten to two ten
Thermocouple.Because the smoke components in waste incineration class power plant are different from conventional thermal power plant, the corrosivity of flue gas is very high.
The thermocouple of conventional material can not long-play because corrosion resistant performance is not strong, therefore in such a flue gas.Normal conditions
Under, conventional thermocouples are typically only capable to run the damage that is corroded in 2-3 months, can not be continuing with.In order to ensure the peace of incinerator
Row for the national games, need to change the thermocouple of damage in time, but frequently changes thermocouple and not only increase operation cost, also can not to burner hearth,
Flue temperature implements continuous accurate measurement.
The content of the invention
The shortcomings that in order to overcome prior art and deficiency, the present invention provide a kind of garbage incinerating power plant burner hearth flue thermoelectricity
It is even, mainly it is placed in the metal including thermode, insulation tube, metal protective sleeve pipe and terminal box, the thermode and insulation tube
In protection sleeve pipe, it is characterized in that, flue gas detection position setting one is located in the end of thermocouple has corrosion proof function
High-temperature wearable metal coating overcoat, protected due to being provided with the high-temperature wearable metal with corrosion proof function at flue gas detection position
Overcoat is protected, therefore greatly adds the service life of thermocouple, both reduces operation cost, while improve temperature survey again
Stability, effectively ensure burn furnace apparatus normal operation.
The technical solution adopted for the present invention to solve the technical problems is：The present invention provides a kind of garbage incinerating power plant stove
Thorax flue thermocouple, mainly put including thermode, insulation tube, metal protective sleeve pipe and terminal box, the thermode and insulation tube
In the metal protective sleeve pipe, it is characterized in that, setting one in the end of the metal protective sleeve pipe has corrosion proof function
High-temperature wearable metal coating overcoat.
Preferred scheme of the present invention is that the high-temperature wearable metal coating overcoat is made up of following material by weight：Cobalt
40%-43%, tungsten 14%-16%, chromium 36%-38%, molybdenum 3%-4%, nickel 2%-3%.
Preferred scheme of the present invention is that the end of the metal protective sleeve pipe is replaced with outside the high-temperature wearable metal coating
Set, it is connected through a screw thread and fixes and in seam crossing between the high-temperature wearable metal coating overcoat and the metal protective sleeve pipe
It is welded and fixed.
Preferred scheme of the present invention is that the high-temperature wearable metal coating overcoat is socketed in the metal protection protector pipe end
Outside and in seam crossing using being welded and fixed.
The beneficial effects of the invention are as follows：The present invention proposes a kind of garbage incinerating power plant burner hearth flue thermocouple, due to
The end of metal protective sleeve pipe is to set a high-temperature wearable metal with corrosion proof function to protect positioned at flue gas detection position
Overcoat is protected, therefore greatly adds the service life of thermocouple, both reduces operation cost, while add temperature survey again
Stability, can effectively ensure burn furnace apparatus normal operation.

Fig. 1 is the structural representation of prior art one embodiment.
Fig. 2-Fig. 4 is the structure chart of one embodiment proposed by the present invention.
Fig. 5-Fig. 7 is the structure chart of second embodiment proposed by the present invention.
In figure：
1. terminal box；
2. metal protective sleeve pipe, 2.1 metal protection protector pipe ends, 2.2 external screw thread connection ends；
3. high-temperature wearable metal coating overcoat, 3.1 overcoat pores, 3.2 internal thread connection ends；

Embodiment
Fig. 1 is the structural representation of prior art one embodiment.Shown in figure, in the prior art, thermocouple mainly wraps
Thermode, insulation tube, metal protective sleeve pipe 2 and terminal box 1 are included, thermode and insulation tube are placed in metal protective sleeve pipe 2.Mesh
Before, refuse-burning plant needs largely to measure the temperature of burner hearth, flue using thermocouple, due to waste incineration class power plant
Smoke components be different from conventional thermal power plant, the corrosivity of flue gas is very high.Therefore, thermocouple can not in such a flue gas
Long-play.Under normal circumstances, conventional thermocouples are typically only capable to run to be corroded for 2-3 months and damaged, it is necessary to often change,
Running cost is caused to increase.
Fig. 2-Fig. 4 is the structure chart of one embodiment proposed by the present invention.Shown in figure, in this example, a kind of waste incineration
Power plant furnace flue thermocouple, mainly including thermode, insulation tube, metal protective sleeve pipe 2 and terminal box 1, the thermode
It is placed in insulation tube in metal protective sleeve pipe 2, it is characterized in that, set one to have in the end of the metal protective sleeve pipe 2 and prevent
Corrode the high-temperature wearable metal coating overcoat 3 of function.Fig. 2, Fig. 3 and Fig. 4 are shown, unlike the prior art, golden in this example
Category protection sleeve pipe end 2.1 replaces with the high-temperature wearable metal coating overcoat 3 with corrosion proof function, and metal protective sleeve pipe 2 has
There is an external screw thread connection end 2.2, high-temperature wearable metal coating overcoat 3 has an internal thread connection end 3.2, outside high-temperature wearable metal coating
It is connected through a screw thread fixed between set 3 and metal protective sleeve pipe 2 and is welded and fixed at seam 4, welding material uses high temperature
Alloy welding wire.
Fig. 5-Fig. 7 is the structure chart of second embodiment proposed by the present invention.Shown in figure, with first implementation of the present invention
Unlike example, in this example, the high-temperature wearable metal coating overcoat 3 is socketed in the outer of the metal protection protector pipe end 2.1
Face and it is welded and fixed at seam 4, welding material uses high temperature alloy welding wire.
Thermocouple proposed by the present invention is can be seen that in above-described embodiment, because the end in metal protective sleeve pipe is ascended the throne
Setting one in flue gas detection position has the high-temperature wearable metal coating overcoat of corrosion proof function, therefore greatly adds
The service life of thermocouple, both reduce operation cost, while add the stability of temperature survey again, can effectively ensure to burn
Burn the normal operation of furnace apparatus.
